I have a 1979 marine application Onan 7.5 genset..engine runs well/good. all of a sudden the voltage started to be irratic..from 50 volts to 110 volts..sometimes it stays at around 110 and just bounces around there but the lights go regular bright to very dim and back and forth...would a voltage regulator do that? or is it a negative/ground problem?..i see a ground wire leading from the outside casing of the generator, i cleaned that up where it connected to my engine block and copper piping, was corroded but didnt fix the problem.
any help would be much appreciated, thanks.
